Title	Placement of loci avenins and resistance to Puccinia coronata to a common linkage group in Avena strigosa
Journal	Genome
Year	1994
Volume	37
Pages	900-903
Author	Rayapati P Portyanko V Lee M
Abstract	Alcohol-soluble seed storage proteins of oat (avenins) were extracted from two diploid accessions representing the A genome and separated by high-resolution acid polyacrylamide gel electrophoresis. Polymorphisms were detected for three clearly resolved protein bands. Linkage analysis of 88 F(2:3) families mapped the three bands to a single locus. Integration of avenin segregation data with an RFLP linkage map constructed from the same population, mapped the avenin locus to a linkage group containing a locus conferring resistance to nine isolates of Puccinia coronata. Linkage between genes encoding alcohol-soluble seed proteins and genes for resistance to Puccinia species was also observed for the homoeologous group 1 chromosomes of barley (1H, rye (1R), wheat (1A, 1B, 1D), and chromosomes 4 and 10 of maize.
